Other Parts Discussed in Thread: AM3358,
Hi,
Customer is designing AM3358+TPS65218D0 for battery backup supply.
There is fast discharging issue of coin cell battery.
You can see green box in attached file for checking supply by coin cell
- VDDS_RTC of AM3358
- EXT_WAKEUP, RTC_PORZn
Could you review the schematic and check why there is fast discharging of coin cell?
